Common Regex Patterns and Their Uses
Regular expressions are powerful tools for pattern matching and text manipulation. Here are some common regex patterns and their uses:
Validate Email Addresses
^[A-Za-z0-9._%+-]+@[A-Za-z0-9.-]+\.[A-Z|a-z]{2,}$Use this pattern to validate email addresses in your forms or data processing.
Password Strength Checker
^(?=.*[A-Za-z])(?=.*\d)[A-Za-z\d]{8,}$Ensures password has at least 8 characters, including one letter and one number.
Match Phone Number Formats
^(\+\d{1,2}\s)?\(?\d{3}\)?[\s.-]\d{3}[\s.-]\d{4}$Matches various phone number formats, including international prefixes.
Validate URLs
^(https?:\/\/)?([da-z\.-]+)\.([a-z\.]{2,6})([/\w \.-]*)*\/?$Use this pattern to validate URLs, including those with or without protocol.
Use our Regex Tester to experiment with these patterns and create your own custom regular expressions for your specific needs.
